Magnetic Precursor to the Structural Phase Transition in V2O3

open access: yesAdvanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

A High Throughput Platform to Minimize Voltage and Fill Factor Losses

open access: yesAdvanced Energy Materials, EarlyView.
A high‐throughput workflow is developed to determine the Langevin reduction factor in organic photovoltaics autonomously and accurately within seconds. Using UV–Vis spectra, current–voltage curves, and transient absorption kinetics, intrinsic charge absorption cross‐sections are calculated.

The Value of Device Characterization for the Optimization of Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Using the example of organic photovoltaics (OPV), this study examines whether and when additional measurements can be helpful in process optimization. A virtual laboratory based on real solar cells serves as a benchmark function to compare two different approaches for process optimization, namely black‐box optimization (black circle) and model‐based ...

Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings. Photovoltaic (PV)

Spin‐Selective Catalysts for Oxygen‐Involved Electrocatalysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The sluggish kinetics of oxygen‐involved electrocatalysis hinders the efficiency of the energy conversion process, which can be promoted by using spin‐polarized materials to conduct spin‐selective electron transfer. This review delivers a thorough and timely overview of state‐of‐the‐art spin‐selective catalysts, aiming to offer a clear route for ...
